You can use most modern types of battery charger on the new AGM (Absorbed Glass Mat) batteries but please check charger instructions first as there may be a particular setting you'll need to select just for the AGM. If your charger is only suitable for lead acid batteries, do not charge AGM or Gel batteries with it as it could prove dangerous. Most of Motorcycle Products chargers cater for all types of battery including wet cell acid type, dry cell & Gel batteries. Please read descriptions before making your choice.
